Kavli Affiliate: Risa H. Wechsler | First 5 Authors: John F. Wu, J. E. G. Peek, Erik J. Tollerud, Yao-Yuan Mao, Ethan O. Nadler | Summary: We present "Extending the Satellites Around Galactic Analogs Survey" (xSAGA), a method for identifying low-$z$ galaxies on the basis of optical imaging, and results on the spatial distributions of […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Anthony Carr, Tamara M. Davis, Daniel Scolnic, Khaled Said, Dillon Brout | Summary: We examine the redshifts of a comprehensive set of published Type Ia supernovae, and provide a combined, improved catalog with updated redshifts. We improve on the original catalogs by using the most up-to-date heliocentric […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Kristine W. F. Lam, Szilárd Csizmadia, Nicola Astudillo-Defru, Xavier Bonfils, Davide Gandolfi | Summary: Ultra-short-period (USP) exoplanets have orbital periods shorter than one day. Precise masses and radii of USPs could provide constraints on their unknown formation and evolution processes. We report the detection and characterization […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Martin C. Weisskopf, Paolo Soffitta, Luca Baldini, Brian D. Ramsey, Stephen L. O’Dell | Summary: Scheduled to launch in late 2021, the Imaging X-ray Polarimetry Explorer (IXPE) is a NASA Small Explorer Mission in collaboration with the Italian Space Agency (ASI). The mission will open a […]
Kavli Affiliate: Donald G. York | First 5 Authors: Varsha P. Kulkarni, David V. Bowen, Lorrie A. Straka, Donald G. York, Neeraj Gupta | Summary: We report {it HST} COS spectroscopy of 10 quasars with foreground star-forming galaxies at 0.02$<$$z$$<$ 0.14 within impact parameters of $sim$1-7 kpc. We detect damped/sub-damped Ly$alpha$ absorption in 100$%$ of […]
Kavli Affiliate: C. L. Kuo | First 5 Authors: J. P. Filippini, A. E. Gambrel, A. S. Rahlin, E. Y. Young, P. A. R. Ade | Summary: Experiments deploying large arrays of transition-edge sensors (TESs) often require a robust method to monitor gain variations with minimal loss of observing time. We propose a sensitive and […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Sylvain Veilleux, David S. N. Rupke, Weizhe Liu, Anthony To, Margaret Trippe | Summary: This program is part of QUEST (Quasar/ULIRG Evolutionary Study) and seeks to examine the gaseous environments of z < 0.3 quasars and ULIRGs as a function of host galaxy properties and age across […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: How does an irreducible representation of a group behave when restricted to a subgroup? This is part of branching problems, which are one of the fundamental problems in representation theory, and also interact naturally with other fields of mathematics. This […]
